Summay:

A theory for faired towcable kiting is presented. Geometric relationships and equilibrium equations are derived based on a think elastic rod-high aspect ratio hydrofoil analytical model.
The fairing section is characterized by torsional and flexural rigidities and hydrodynamic lift, drag, and moment coefficients. The presence of asymmetry (camber) also is accounted for. Predictions of towing configurations are presented. It is shown that small angles of attack (.15 degrees) can result in kite angles up to 60 degrees and catenary depth losses of 10 to 15 percent. Remarkably small camber (.1 percent of chord) is sufficient to cause significant kiting. Stability criteria are developed based on an analysis of the torsional buckling problems associated with the structural rigidities. The results have important implications in the design of towcable strength members and fairings.
